[nm matt]

They look like a clone of Sugino's OX series cranks, based on the specs. IRD's site says they will fit 68 or 73mm shells (Sugino won't fit 73mm IIRC) so might be more useful on some frames. Since you can have whatever rings you like, presumably IRD is holding stock and may even sell spares(!), but I'm speculating.

Other than price, 73mm shell compatibility, and the ability to mix and match chainring and crank colours, the main advantage is that one can get rings smaller than 44x30 as stock. Lobos are now cheaper than OX601D (at Soma online), so the Suginos must have gone up recently. :-(

There's no mention of Q factor at either IRD's site or Soma's, and I'd want to know that before buying anything.

[rant] IRD's website is very poorly supplied with useful information; surely it wouldn't kill them to list more complete specs. There don't appear to be any photos of the back of the RH crank, spindle, or LH crank attachment or adjustment system anywhere either. [/rant]

IRD does sell spare rings for them, they just aren't listed on the Soma store.  I emailed them directly and got pricing (they are a bit cheaper than Sugino rings).

The Sugino OX601d Q-factor is in the 150ish range, and I'd expect the IRD to be about 5mm wider.  The design is very similar, but the IRD has a longer spindle to handle 73mm BB shells.

A Ritchey Logic Compact on a 103mm BB is a lot narrower, and even more so on a 98mm BB.

Thanks - I might see if I can get some. :-)

The Sugino OX601d Q-factor is in the 150ish range,

^ Sugino claim the OX series cranks are 145mm, but I haven't measured to check; the defunct ZX-801D MTB variants had a wider chainline, would fit a 68 or 73mm shell and were supposed to be 156mm.

and I'd expect the IRD to be about 5mm wider.  The design is very similar, but the IRD has a longer spindle to handle 73mm BB shells.

They might make good low Q MTB cranks, on frames with narrow enough chainstays.

A Ritchey Logic Compact on a 103mm BB is a lot narrower, and even more so on a 98mm BB.

On a 107mm Shimano UNxx BB I measure Q for Logic Compact cranks to be ~155mm, so I'd expect ~151mm on a 103mm 7410 BB and ~148mm on a Record/Chorus 102mm ISO BB; IIRC Nick said his are 146mm on a 98mm Phil BB, however Phil didn't respond to my emails asking if 98mm BBs were still available, so I wouldn't hold out too much hope there.  :-(

I just swapped the Ritchey Logic Compacts for Sugino OX-601d on one of my bikes and can say that the arms are noticeably farther from the chainstays with the Sugino cranks.  The arms are also thicker.

I was using a 103mm Dura-Ace BB (7410 I think) that was modified by removing the shoulder from the right cup.

I doubt that I'll have time to make better measurements soon, but will try if I get bored.

I just made a couple of quick measurements on a couple bikes in the garage:

Sugino OX801d cranks, fitted to a BB386EVO frame with Wheels Manufacturing screw together angular contact BB: 146.5mm

Ritchey Compact Logic cranks on a Phil Wood 98mm BB: 146mm

The narrowest cranks I have are a pair of Ritchey Logic 110BCD - double, not triple, there's no provision for mounting a third chainring - on a 107mm BB Q for those is 140mm.

[Mike Schiller]

they look nice and It's great to start seeing more sensible cranksets on the market. Too bad they are over $300.  Guess I'll stick with my 94 BCD 90'  MTB cranksets.

Q sounds good to me. Anything less than 150 mm hurts my knees.  Actually I'm pretty happy at 200 mm on my Ritchey Fat bike.

I recently scored an NOS set of Shimano Deore touring cranks from the early 1980s, the ones that use the 50.4mm BCD and take TA chainrings. I got them cheap because they were built for use with dynadrive pedals, which no longer exist, but I also separately found a set of adapters so that normal pedals can be used. Installed on a 122mm BB gives the right chainline when setup as a double and the Q is about 145mm:

[Stephen Poole]

Nice! I'm sure *some* DD pedals still exist, though they haven't been available new for 30 years or so; I always thought they were a cool idea. In fact, there are a few on eBay right now, Deore included, but most of the prices are scary. 8-(

Out of idle curiosity, I wonder if those cranks would work with the Sun XCD 110/74 spiders?

Later,

Stephen (who's slightly tempted to get some Lobo cranks during Soma's next 20% off sale to check them out)

[satanas]

Has anyone seen or used the IRD Lobos yet? There's precious little info on the IRD site...

[Jeremy Tavan]

I bought a set (black, 172.5, 46/30) but the project they were intended for went a different direction. Still have them around, waiting to see if I find a project that needs a black crank set, or a buyer who wants a black crankset. Is there anything specific you'd like to know?

/Jeremy

[Stephen Poole]

Hi Jeremy,

I'd really like to know two things:

1. The Q factor (outside to outside at the pedal eyes, in mm), and

2. The distance between the insides of the cranks at the pedal eyes, again in mm

The second one is more important as that decides what frames the cranks will clear, and by how much. I'm not keen on having a set freighted here to Oz and then discovering they won't fit.  :-(

Thanks,

Stephen

[Jeremy Tavan]

I'm out of town on vacation for a couple weeks, but would be happy to take those measurements when I get back.

[Stephen Poole]

Thank you.  ;-)

Looks nice, but $329 seems pretty up there.  There are other options for a wide-low double that won't empty your wallet so much.

I realize that's not what you asked but just giving my opinion.

I'd be more likely to cough up $179+shipping but there's no way I'm paying $329 unless it's made from genuine unicorn tears or something.

^ Other than old triples minus the outer ring (i.e., used, fairly high Q), VO or the cheap FSA square taper cranks, there are no cheap-ish subcompact options. It would be great if Shimano would make something, and I'm not the only one who's thought this.

As for unicorn tears making good structural beams, I have no data...

   How cheap are we talking here? The 94 BCD IRD Mjolnir sells for under $200 new.

[Stephen Poole]

Which is fine provided you're happy with 175mm - the only length - and one chaining (not included). There are better options otherwise IMO, and if you just want a 94 bcd crank there are plenty of used MTB cranks out there, if low Q isn't mandatory.

In my case, I'm wondering if the Lobo might fit a Salsa Cutthroat frame; this has a pressfit BB and requires the use of a 24mm axle crankset, and most/all road cranks won't fit as they would hit the chainstays. If the Lobo has a bit higher Q (there's no published info that I've found), then it might be useful there, and if it's low Q it might be good for other things. My guess is it probably falls somewhere in the middle, and I'm not prepared to buy some to find out. :-(

[Chris Leydig]

Sorry if revitalize this thread, but I can't get any response from IRD on this. Does the lobo allow for a 24t aftermarket granny ring? I'm trying to setup a 40/24 (mtb). At 74bcd it should but the site implies it can only go down to 28t.

[Bicycle Touring Explorer]

yes IRD sells spare rings for them and look on https://www.bikeparts.com/

[satanas]

Unless IRD are lying about the BCD being 110/74mm, then a 24T inner should indeed fit - whether IRD sell them or not. There are plenty of other sources, like TA, etc.
